T0 all w7wm it ma.y concern:

Be it known that I, HORAOE H. J UDSON, a citizen of the United States,residing a.ta Stratford, in the county of Fairfield and Sbate 0fConnecticut, have invented eertain new and nsefnl Improvements inSbretchers for Invalids; and I (10 hereby declare the following t0 be afull, elear, and exact deseription 0f the invention, such as will enableothers skilled in the arb 150 which ib appertains t0 make and use beSame.

My invention has f01 its objecl: 130 produee a streteher for movinginvalids 01 patients '00 be operated upon without; lifting them from thesheet, ib being 0f obvious importance that; such a (leviee be simple ineonstruction, 0f little cost, and easily managed. lt is 0f course weilnnderstood that; in all classes 0f serious illness or injury ib isfrequently neeessary bhat; Lhe patienb should be lifted froxn Ehe bed.'Ihis has in many cases had t0 be done by mein strength-that is, bylifting the patienb in Ehe armswhich in many cases canses intenseSuffering 150 bhe patienb, and, in the case 0f adults, requires greatphysical strength 0n the parb 0f the person 0r persons lifbing thepatient-.

The most importzant result: aceomplished by my invention is that; I amenabled t0 avoid all lifting 0f Ehe patienb by mein strengthand providea simple means for moving the patienb withouta the necessiby of bisbeing lifted from the sheet upon Which he is lying. 'Ihis I accomplishby the simple and novel construction of which thefollowing deseription,in counection With the accompanying drawings, is a specification,numbers being used to indicate the seveml parts.

Figure 1 is a plan view illnstrating the several parbs 0f the stretcherdetached; Fig. 2, 2b similar view illustrating the manner in which thestretcher is used, and Fig. 3 is a cross-section 0n the linex a; in Fig.2.

My novel sbretcher consists 0f fonr parts and a supporting-piece, whichmay be the usual under sheeb of abed. Tl1e parts are two side strips,denoted by l, and t;wo holding-braces, denoted by 2.Thesupporting-pieceis denoted by 3. 'lhe side strips are made alike andmay l0e 0f any desired form. I preferably make Ehe main portion angular,es ab 4, provicle ab each end reduced squared portions 5,which are en-Serial N0. 241,580. (N0 model.)

gaged by the braces, and also handles (i f0l eonvenienee in use. Theseside pieees may be made 0f mebal 01 w0od, but preferably 0f light strengwood. The braces are preferably made 0f mebal and bifurcated at theirends t0 enable them 150 engage the side pieces firmly. The braces may bemade in a Single piece, if preferred; but I ordinarily make each br:1ceof two pieces and provicle a joint, 7, als the senter, made likeacarriage-joint, es ab the left in Fig. 2, or else forma right and left:screw-bhreads, respecbively, ab the ends 0f bhe parts, which areeng-aged by corresponding t-hreads in a nnt, 8, as in Fig. l and ab therighb in Fig. 2.

The operation 0f rny improved stretcher is as follows, two persons onlybeing required to move an adult from a bed wibh ease and WithoubjarringEhe patienb: 'Ihe portions of Lhe sl1eel; ab the head and foot of Ehebed are designated in the drawings by 3that is, the portions of thesheet th2it are orclinarily tucked around the mattress ab the head andfoot 0f the bed. In using bhe stretcherthey are foldecl over, es shownin both figures. Euch 0f tahe side pieces is oben taken by bheattendants 2blld rolled up in the sheet, as clearly shown in Figs. 2 und3. As the side pieces am ordinarily made angular and Ehe sheet is(loubled overat both ends, 110 additional devices whatever are required130 secure Ehe sheet t0 Lhe sidepieces. \Nhen Ehe sheet'has been rolledsufficientl y 011 both sicles, es in Fig. 2, the braees are placed inengagemenb with the portions 5 of Ehe side slarips, the et'fect of whiehis t0 hold the side pieces finnly, thereby making ofbhe side pieces,

braces, anti sheet a perfectly firm and stable tion shown in dottedlines '00 the posibion in 5 full lines. \Vhen the 1ight and lefbthreacled nut is used. es ab the right, the nnt has to be turnedsuffieiently throw ont the two parts 0f the brace unbil the side piecesz1re eaused to hake up the slack in the sheet.

Having .thus described my invenbion, I claiml. A strebcher consisting ofa supporbingdles 6,and ad justable braces bifurcat'ed ab their 10piece,as a sheet,two side strips adapted to be ends, be parus of whichare forced outward by rolled in the sheeb from opposihe sidesand adarighb and left1 Lhreaded nuta. juStable braees which engage the sidestirips 130 l In testimony whereof I affix my signature in 5 hold themfirmly and pressthexn oubward t o presence of 11w0 wibnesses.
